Rose plant -- Meitifran variety

ABSTRACT

A new and distinct variety of rose plant of the Miniature Class is provided which forms in abundance highly attractive bicolored very double blossoms. The blossoms are white in coloration and bear bengal rose edges. The plant has glossy foliage, reflowers well, and forms blossoms having an umbrella configuration when fully open. The central petals tend to be tapered and small. The new variety is particularly well suited for use as attractive ornamentation when grown as a flowering pot plant either indoors or outdoors.

SUMMARY OF THE INVENTION

The new variety of Miniature rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the Magic Carrousel variety (U.S. Plant Pat. No. 3,601). The male parent (i.e., the pollen parent) of the new variety was the product of the pollination of the Alain variety (non-patented) by Rosa mutabilis on the one side and the Medar variety (non-patented) by the Caprice variety (non-patented) on the other side. The percentage of the new variety can be summarized as follows:

    [Magic Carrousel]×[Alain×Rosa mutabilis)×(Medar×Caprice)].

The seeds resulting from the above pollination were sown and 137 plantlets were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Miniature rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance on a continuous basis attractive very double bicolored blossoms which are white with bengal rose edges, have small central petals, and assume an umbrella configuration when fully open,

(b) exhibits a bushy growth habit, and

(c) forms glossy foliage.

The new variety well meets the needs of the horticultural industry for many usages. It is particularly well-suited for use as attractive ornamentation as a flowering pot plant for use indoors or outdoors.

The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the Meitifran variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety described herein were two years old and observed during June while growing on their own roots outdoors at Cannet-des-Maures, Var, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The terminology which precedes the chart information has been added to indicate the colors in common terms. The description is based on the observation of two year old specimens of the new variety during June while growing outdoors on their own roots at Cannet-des-Maures, Var, France.
